Solution Overview

Problem

The existing dashboard design encroaches on the display surface due to the placement of vents, which limits the available display area for information display screens.

Innovation Solution

A dashboard arrangement featuring a movable deflector between the display screen and the vents, allowing for adjustable air diffusion directions by pivoting up or down, with motorized drive means for precise control, thereby optimizing the use of display space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If vents are placed on either side of the information display screen to distribute air throughout the passenger compartment, then air distribution function is improved, but the display area is reduced due to encroachment by the vents

Engineering Contradiction:

Improveair distribution functionVSAvoiddisplay area

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent moves the air vents from a lateral position (left-right of the screen) to a rear position (behind the screen), utilizing the depth dimension of the dashboard. This spatial reconfiguration allows the vents to be positioned at the rear edge of the dashboard, behind the display screen, thereby eliminating encroachment on the display area while maintaining air distribution functionality through the passenger compartment

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If vents are positioned at the front near the windshield to maximize display area, then display area is improved, but air distribution effectiveness to the driver area may be reduced

Engineering Contradiction:

Improvedisplay areaVSAvoidair distribution effectiveness

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The patent introduces a movable deflector as an intermediary element positioned between the rear vents and the passenger compartment. This deflector can be adjusted to various angles to optimize air flow direction, ensuring effective air distribution to the driver and passenger areas while allowing the vents to be positioned at the rear for maximum display area

Inventive Principle:

Principle #24Intermediary (Mediator)

Applied Scientific Principles
